' The same letters denote the same parts.

I have heretofore, December 11, 1877, No. 198,113, obtained LettersPatent for an improved boiler-feeder by means of which the water can besupplied to the boiler without using a pump. The present feeder is animprovement upon the one referred to, in that it is automatic in itsoperation.

In the drawings, A represents the boiler; B, an inclosed tank above thewater-line of the boiler; 0, another inclosed tank above the tank B, andD a chamber above the tank 0. The chamber D is preferably inolosed.

EE represent a pair of vessels, attached by means of the arms 0 e to theshaft F. The shaft is journaled in the walls at cl of the chamber D, andoutside the walls the shaft is furnished with the cranks ff. The shaftF, carrying the vessels E E, can be oscillated in itsbearings, and so asto bring the vessels E E alternately upward in an upright position abovethe shaft F and downward in a reversed position below the shaft F.

A pipe, G, leads from the boiler A to the tank 0, an exhaust-pipe, H,leads from the tank 0 to the open air, a pipe, 1, leads from D to thetank 0, a pipe, J, leads from the tank O to the tank B, and a pipe, K,leads from the tank B to the boiler A. The feed-water is suppliedthrough the pipe L.

The operation is as follows: The feed-water flows from the pipe L intothe upper one of the vessels E E. As shown in the drawings, it is thevessel E. The vessels E E are shaped so that after being suitably filledwith the feedwater they will become unbalanced, and in consequence causethe shaft F to turn in its bearings. To this end the vessels E E may beshaped as shown in Fig. l more distinctly-- that is, be enlarged at theupper end, at one side of the center, as shown at E. As the vessel Ebecomes filled in the part c, the shaft F turns, causing the vessel E tobe carried downward below the shaft F and its contents to be dischargedinto the chamber D. As the vessel E is thus carried E is carried upwardand into the position previously occupied by the vessel E. The vessel Eis now filled and the operation repeatedthat is, the vessel E is carrieddownward, its contents discharged, and the vessel E brought upwardagain. The projection e in the vessel E is, when the vessel is above theshaft, on the opposite side to that on the vessel E. This causes theshaft F to oscillate and to move the accordingly. As the cranks ff arethus moved reciprocatin gly,they encounter the handles 9 g and h h ofthe valves g and h of the pipes G and H, respectively-that is, in thepipe G there is a valve, g by means of which the flow of steam from theboiler to the tank 0 is regulated, and in the pipe H there is a valve,W, by means of which the exhaust from the tank 0 is regulated. The valveg has a two-arm handle, 9 g, and the valve W has a two-arm handle, it h.

The operation is as follows: As the shaft F turns one way the cranks ffoperate on the valves g h to close the pipe G and open the pipe H. Thewater then flows from the chamber D past the check-valve i in the pipe 1into the tank 0. As the shaft F turns back, the cranks f f act to openthe valve 9 and close the valve h. The same steam-pressure then existsin the tanks 0 D as in water flows from the tank 0 into the tank D, andthence into the boiler A. The water continuing to flow from the pipe Linto the upper one of the vessels E E, the shaft F is turned again, andthe operation of filling and emptying the tank U is repeated, and so on.

The arms 6 e are preferably furnished with extended surfaces e (a -sayin the form of a flat strip-for the purpose of gradually checking themovement of the vessels E E in their alternating movement. The strips 0encounter the water in the chamber D, and thus gradually arrest themovement of the vessels. The water-line in the chamber D is indicated bythe broken line 61, Fig. 1. The rising of the the boiler, and the ICOWater above the level indicated is prevented by the overflow-pipe d. Themotion of the shaft F or the vessels E E might be commnnieated to thevalves g [t in any suitable manner. I consider, however, the means shownthe most desirable. The two positions of the handles g g or it 7t areshown in Figs. 3 and 4, respectively. Any suitable stop may be used forpreventing the vessels E E from rotating too far. The pipe L for thispurpose may be extended at l to come in the \vayot' the strips- 0 6 asshown. The water might flow from the tank G directly into the boiler A,-but I prefer to have the water delivered first into the tank B, asshown. This lastnamed tank maybe larger than the tank C,and sufficientlylarge to enable the Water to accumulate there or to come under theintluence of the heat of the steam ot' the boiler, and thereby becomeheated bet'ore entering'the boiler. Should the Water rise too high inthe tank 13, the ball-lever M acts through the connection at and valve mto check the flow of Water in the pipe L. The pipe J is provided with avalve, j, forclosing the pipe J when desired. This valve j may be acheck-valve seating upward, similar to the valve i in the pipe I.

I claim- 1. The combination of the chamber D, the

shaft F, and the oscillating pair of vessels E d, in combination withthe i and for the purpose described.

3. The combination of the chamber D, the shaft F, the vessels E E, thecranksff, the valves g b and the pipes G H, substantially as described.

4. The combination of the chamber D, the shaft F, the arms 0 c, thevessels E E, and the strips 0 0 substantially as described.

5. The combination of the chamber D, the shaft F, the arms 6 c, thestrips 0 c and the stop Z, substantially as described.

6. The chamber-l), having the overflow-pipe vessels E E, substantially7. The oscillating as described. pair of vessels E E, havingtheenlargementc, in combination with the chamber D, as and for thepurpose described. 8. The combination of the chamber D, the oscillatingshat't F, the cranksff, the valves [L2, having the two-part handles 9 gh h, and thepipes G H, substantially as described.
